CVE-2013-1670: n/a vulnerability

CVE-2013-1670: The Chrome Object Wrapper (COW) implementation in Mozilla Firefox before 21.0, Firefox ESR 17.x before 17.0...

The Chrome Object Wrapper (COW) implementation in Mozilla Firefox before 21.0, Firefox ESR 17.x before 17.0.6, Thunderbird before 17.0.6, and Thunderbird ESR 17.x before 17.0.6 does not prevent acquisition of chrome privileges during calls to content level constructors, which allows remote attackers to bypass certain read-only restrictions and conduct cross-site scripting (XSS) attacks via a crafted web site.

Security readout for executives and security teams

This is an old Mozilla client-side browser/mail client flaw. A crafted website could bypass intended read-only boundaries and gain elevated browser “chrome” privileges, enabling cross-site scripting against affected Firefox or Thunderbird versions. Exposure is limited to legacy systems still running Firefox before 21.0, Firefox ESR 17.x before 17.0.6, Thunderbird before 17.0.6, or Thunderbird ESR 17.x before 17.0.6. Prioritize remediation where legacy browsers or mail clients remain in production. Modern supported environments should have low residual exposure, but unmanaged legacy endpoints can still create user-driven compromise risk. Mitigation focus: Upgrade Firefox to 21.0 or later, or ESR 17.0.6 or later.; Upgrade Thunderbird to 17.0.6 or later where deployed.; Apply relevant Debian, Ubuntu, Red Hat, SUSE, or Mandriva security updates..
